Note: The two sections below (Derived Stats and CLASSIC Attributes) are quite complicated, and covered in both the melee and ranged section of this guide. There’s nothing different between the two, so if you read this stuff while reading about ranged characters, feel free to skip down to Ranged Builds.
Derived Stats
Before getting into melee-specific stuff, I’ll cover the derived stats we have to consider when making a character in WL2:
Combat Initiative: Combat initiative depends when in combat you act, and also how often you act. Combats are split into segments during which a 6 CI character will act 10 times and a 20 CI character will act 33 times.
Max CI character (20) = 33 turns
High CI character (15) = 25 turns
Average CI character (10) = 16 turns
Low CI character (6) = 10 turns
(Data from Mambus’s tests - thanks. Note that these are not break points - a CI12 character will act approximately 20 times per Segment. I have heard some people reference break points like, enemy melee tends to have 15 CI and ranged stuff tends to have 10 CI, so if you have 16/11 you'll act before them, but I'm not sure how consistent this is or whether it remains constant across difficulties.)
Action Points: Action points control what you can do when you act. Firing an M16 Assault Rifle costs 5 AP. Firing it in burst mode (3 shots, but with an accuracy penalty) costs 7 AP. Attacking with Dragon Claws, a Brawling weapon, costs 3 AP.
CI vs AP: CI and AP tend to balance one another out - if they’re roughly equal, 1 AP is worth 2 CI. If you had a weapon that cost 1 AP to fire, ideally you’d stick to a CI/AP balance that looked something like this:
10 CI 05 AP
12 CI 06 AP
14 CI 07 AP
16 CI 08 AP
18 CI 09 AP
20 CI 10 AP
The simplest way to explain why this is an optimal balance is that AP and CI both cost the same amount, so if you invest heavily in one you get a table that looks something like this (in concept):
5*5 = 25
5*6 = 30
5*7 = 35
5*8 = 40
5*9 = 45
Or, alternatively, if you balance the two, your table looks more like this (in concept):
5*5 = 25
5*6 = 30
6*6 = 36
6*7 = 42
7*7 = 49
In the real world, of course, you don’t have 1 AP weapons, so instead you tend to optimize AP around the cost of firing the weapon(s) you’re planning to use, and pump the rest of your points into CI to act as often as possible.
Damage: Damage controls how much damage you do when you attack. It’s primarily obtained by acquiring new weapons. If you’re melee, Strength increases the weapon min and max damage by 2% per point, rounding down. If you’re using Brawling, level increases min/max damage you do by 1 per level, but this is not modified by Strength.
Armor: If the Armor Penetration value on your weapon does not meet an enemy’s Armor value, your attack does substantially reduced damage: -20% for the first point of armor you do not penetrate, -10% each for the next two, then back to -20% per point. This means that if you're attacking an Armor 7 target with a Penetration 1 weapon, you will deal no damage.
Skill Points: Skill Points are used to train Skills. These include weapon Skills (your base hit/crit chance increases), and non-combat Skills (e.g., fixing computers, unlocking doors, etc). Some non-combat skills are essential to progress through the game (e.g., Perception, Demolitions, Lockpicking), and some are only used very rarely (e.g., Animal Whisperer).
Charisma: If we want to recruit certain NPCs, we have to meet specific total-party charisma threshholds. If we do this at all, we’ll dump a lot of charisma on a single character.
A perfect character would have very high AP, CI, and damage. This would mean it could take very long actions, and act very frequently during a segment. It would also have very high Skill Points and Charisma, so we could take all of the Skills we wanted to and recruit all the NPCs we were interested in.
Unfortunately, we have to be a little more selective when designing characters - Wasteland 2 uses a system in which 7 Attributes (CLASSIC) start at rank 1, and characters have 21 points to spend on improving them. They also gain a single Attribute point every 10 levels, meaning characters start the game with 28 Attribute points and tend to finish the game with 32 Attribute points.
CLASSIC Attributes:
[Note that characters start with 3 base AP, 5 base CI, and ? base Con + 3? Con/lvl]
As well as the benefits mentioned below, Strength, Speed, and Intelligence give 0.25 AP per point, combined. This means SSI (sum of Strength, Speed, and Intelligence) should be divisible by 4 to maximize AP gain.
Coordination (1% ranged hit and 0.5 AP per point) is one of the three primary combat attributes in WL2. As it starts at 1, all characters will take it to at least 2 for +1 AP.
Luck (1% crit and some meaningless stuff per point) is a bad investment for combat focused characters.
Awareness (1 CI and 0.5% Evasion per point) is one of the three primary combat attributes in WL2. Generally, SSI will result in an AP/CI balance skewed towards AP, and characters will invest more into Awareness than Coordination to balance it back out.
Strength (0.25 SSI-AP, 3? base Con OR +1 Con/lvl, 2% melee weapon damage, and 10% melee critical strike multiplier per point) is mediocre for ranged characters and excellent for melee characters.
Speed (0.25 SSI-AP, 0.1 Combat Speed, 1% Evasion, and 0.5 CI per point) is one of the three primary combat attributes in WL2. Thanks to the SSI mechanic, 4 Speed returns the same amount of CI/AP as 2 Coordination and 2 Awareness, as well as granting Evasion and Combat Speed. This makes it the best Attribute in the game.
Intelligence (0.25 SSI-AP per point, 2SP/level base, 3SP/level at 4, 4 SP/level at 8, 5 SP/level at 10) is used purely to gain more Skill Points. This is somewhat combat relevant because you have to invest Skill Points into weapon Skills to gain base hit/crit chance.
Charisma is not combat-relevant.
From here, basically we want to figure out how to convert the Attribute points we’re given into the most effective derived stats possible.
Melee Builds - Maximum Damage:
The melee build I’m using in my current game is:
C L A S S I C
2 1 4 9 S 1 1 [9 AP, 14 CI]
My future plan is to put points at level 10, 20, 30, and 40 into Awareness.
Figuring this out was mostly an intuitive process:
* I ignored Luck and Charisma, because they both do very little in combat.
* I decided to run 1 Intelligence and cover the skills required on the rest of my party. This is kind of sad, but melee characters gain a lot more damage from Attributes than ranged characters.
* This means the only stats we have left to figure out are Speed, Awareness, Coordination, and Strength.
* 1 -> 2 Coordination is too good to pass up on, 1 AP for 1 Attribute.
* Speed is incredible for melee - 10 points gives 5 CI and 2.5 AP, as well as some Combat Speed and Evasion, so I really want that. Basically 4 Speed is better than 2 Coordination 2 Awareness, because it gives the same derived AP/CI, AND Combat Speed/Evasion. We know we want CI and AP, so Speed is a great investment.
* So right now I have 11 points left to spend in Awareness and Strength. I could go for 5 total Strength (hitting 16 SSI), and then 8 total Awareness (hitting 18 CI), or 9 total strength (hitting 20 SSI), and 4 total awareness (hitting 14 CI). I actually opted for the latter and figured I’d dump all my extra Attribute points on level up into Awareness. This was partially because I wanted 9 AP for 3x 3 AP attacks.
So, let’s see how my decisions look on a spreadsheet:
At level 10, with 7 Brawling and the CLASSIC attributes above (+1 Awareness at L10):

At level 20, with 10 Brawling and the CLASSIC attributes above (+2 Awareness):

At level 35, with 10 Brawling and the CLASSIC attributes above (+3 Awareness):

To explain these columns:
* Damage per AP should be obvious.
* Damage per AP adjusted by accuracy is just damage adjusted by average miss chance.
* Armor doesn’t currently do anything in my spreadsheet, so let’s ignore that and assume we’re hitting a target with Armor equal or below our Armor Penetration.
* Attacks per activation and Damage per activation respect AP costs. So Rebar Knuckles “waste” 1 AP per activation here. The 3 AP weapons look pretty great, because we have 9 AP per activation.
* Damage per Segment is where we start to account for CI. In a segment, a 6 CI character attacks 10 times. A 20 CI character attacks 33 times.
* I also added a hypothetical column - damage per segment by AP only. This is like, “What if we could attack 2.25 times with Rebar Knuckles per activation, instead of just 2 times and wasting 1 AP”. I think this is quite relevant for melee, as they often have to move and actually won’t be able to optimize AP usage as well as ranged characters can.
Anyway, we can see that damage here looks pretty respectable. But what about with some other statlines?
I thought about starting with something like:
C L A S S I C
2 1 8 5 S 1 1 [8 AP, 18 CI]
But the problem with this is that when we hit level 30, we only have kind of awkward Attribute point spends available - we’d be getting Strength without hitting SSI threshholds, or we’d get 0.5 AP from coordination which does nothing. So what about:
C L A S S I C
4 1 6 5 S 1 1 [9 AP, 16 CI]
This gives us 9 AP 16 CI, but we drop some crit damage/weapon damage from strength. It also lets us finish with 20 CI at level 40. Basically this is trading damage from Strength for higher CI, and keeping our AP at 9 using Coordination.
At level 10, with 7 Brawling and the CLASSIC attributes above (+1 Awareness at L10):

At level 20, with 10 Brawling and the CLASSIC attributes above (+2 Awareness):

At level 35, with 10 Brawling and the CLASSIC attributes above (+3 Awareness):

So okay, this is a pretty noticeable damage loss. I think the main problem is we lose 1 AP from 4-SSI (Strength), and have to replace that with Coordination before we can start boosting Strength. I also experimented with trading 4 Strength for 4 Awareness, but obviously the results are similar to trading 4 Strength for 2 Coordination and 2 Awareness.
So… what’s left to look at? We now know that losing Strength or Speed for Coordination or Awareness is a damage loss. But what if we could trade out Speed for Strength? Based on the numbers above losing 2 Speed for 2 Strength would probably be a damage gain - we’d keep the same amount of AP, but trade 1 CI for 2 points of Strength resulting in extra damage. But uh, we already have 9 Strength 10 Speed, so there’s no space to do that.
This means that at this point I'm very confident in saying that if you're running a melee character with 1 int, the best attribute spend for raw damage is:
C L A S S I C
2 1 4 9 S 1 1 [9 AP, 14 CI]
This left me with just progression to investigate - with Strength-damage seeming so powerful, should I really be dumping all 4 extra points into Awareness, or is it worth putting an extra point in Strength even without the SSI-based AP gain?
I run some quick tests (didn't really want to screenshot everything since it's just one number changing), and it turns out that Awareness is more damage at level 10, 20, 30, and 40.
Melee Builds - Increased Utility:
With that figured out, I’m going to take a look at what happens if you want 4 Intelligence on your Brawler. We know Strength and Speed are both great stats, so the first statline I’m going to look at is:
Level 20:
C L A S S I C
2 1 6 8 8 4 1 [9 AP, 15 CI]
I feel like level 20 is a reasonable place to start - I’ll only bother checking out level 10 or 35 here if it turns out we have stat values that are super close.

From here, we could drop 4 Awareness for 2 Strength 2 Speed. This would leave us with 10 AP 12 CI, and certainly be a damage loss both theoretically and in practise, since most Brawling weapons are 3-4 AP.
I also try changing Strength to 10 and Speed to 6. This increases our theoretical damage output from 9694 to 9714. We also pick up more Con, but we lose Combat Speed and Evasion. I don’t think the Combat Speed loss is worth taking, since it will often translate into directly lost AP and lower damage output.
We also know that losing 4 Strength for Coordination/Awareness would be a damage loss from our prior tests, and losing 4 Speed for Coordination/Awareness would be a utility (Combat Speed, Evasion) loss for no gain.
At this point, the only viable thing left that I haven’t tried is losing 2 Strength for 2 Speed, but it turns out this reduces our theoretical Dragon Claw damage by about 250~. So I’m pretty happy to recommend:
C L A S S I C
2 1 4 8 8 4 1 [9 AP, 13 CI]
As a starting Attribute spend for a Brawler with 3SP/Level.
edit:
A few other posters raised this point and I agree:
C L A S S I C
2 1 4 6 S 4 1 [9 AP, 14 CI]
Loses about 2.5-5% damage, but gains 0.2 Combat Speed and some Evasion. This makes it at least worth mentioning. Perhaps the 0.2 Combat Speed earns back the damage lost through AP saved by paying less to move. I'm not sure.
In terms of future progression, +4 Awareness is basically the only viable option for all of these builds. Going for 3SP/Level (4 instead of 1 int) costs us about 10% of our character’s damage.
Cheers,
Phil
P.S - (If you’re interested in how I ended up with these numbers, the spreadsheet is available at https://www.dropbox.com/s/afat65wmix774d5/WL2.xlsx but it’s nothing particularly complex, just summing sources of hit/crit, multiplying likely crits by the modified weapon crit multiplier, etc).
